for NextGen Batteries

for eAerospace and eMobility Applications

With the surge in US adoption of Renewables and Electric Vehicles (EVs), a glaring reality emerges that there’s an acute shortage of domestically available critical battery raw materials to meet the massive future US eMobility battery demand.

CarbonX is an ultra high-capacity Lithium-Sulfur battery cathode technology to enable the development of high energy density, low weight Next Generation eAviation, 3C and EV batteries. The CarbonX Li-S cathode can be coupled with new Solid-state or ionic electrolytes, Li-metal, and/or high-capacity silicon anodes to enable the production of next-gen batteries made in the USA.

Introduction To Our Technology At Xponential Battery Materials
CarbonX Li-S Cathode Electrode Material

Proprietary porous cryogel structure made from lignin or tannin bioproducts in the paper and agriculture industries, and doped sulfur byproduct from the petroleum industry into a superior Li-S cathode material, that is environmentally friendly and nickel and cobalt-free.

Introduction To Our Technology At Xponential Battery Materials

Superior Battery Materials using Low Cost, US Made, Sustainable Byproducts

“A focus on sustainability. Batteries are a major tool in the challenge to decarbonize the mobility sector and other industries – a task that is essential to avoid triggering irreversible climate tipping points.

The battery revolution could reduce cumulative greenhouse-gas emissions by up to 70 GtCO2e between 2021 and 2050 in the road transport sector alone.

However, the battery industry will need to prioritize the decarbonization of its own industry to maintain it’s credibility”
